'Specificatiomof Letters Patent. I pat fi Auo'. 1 3,

To all whom it may concern Be it known that I, PETER K. ()EECHNA, a subject of the Emperor of Russia, (who has declared his intention of becoming a citizen of the United States) residing Schenectady, in the county of Schenectady and State of New York, have invented-(agre is a specification.

My invention relates particularly to the running gear of automobiles and especially "to that part of the running gear known as the shock absorber.

The object of my invention is to so mount the running wheels that they may be yieldingl'y supported in a novel way whereby the vehicle'may"be madeeasy running and cornfortable.

In carrying out my invention I mount the rear wheels on stud axles, each of which is attached to a lever mounted in a suitable casing and spring supported in such manner 25 as to normally hold it in a horizontal position. When the vehicle is occupied or loaded, the springs are put under compression or tension and. when obstructions are encountered the springs cause the levers to swing with easy" movement in such a way that shocks are effectually absorbed. The stud axles of the rear wheels are geared to the drivingaxle which maybe actuated in anysuitable way.

The front or steering wheels, as usual, are mounted on stub axles which are jointed to brackets projecting horizontally from levers pivotally mounted in casings attached to the under frame of the vehicle. These levers are yieldingly sustained'by springs both above and below them in such, manner as to cause shocks to be absorbed when obstructions are encountered.

In the accompanying drawings, Figure I shows a side'elevation of 'so much of an automobile, with my improvements applied, as is necessary to illustrate my invention. Fig. 2 shows a top plan of the running gear shown in Fig. 1 with my improvements applied. Fig. 3 is a detail view on an enlarged scale partly in plan and partly in horizontal section illustrating the manner in which the front or steering wheels are connected with their shock-absorbers. Fig. 4 is a perspective View of the pivoted lever forming part of one of the shock absorbers slotted to'allow the stu Application: filed; January e, 1918. semi No. 74am.

to which thefront or steering wheels are connected. Fig. 4? is a detail view of the lever shown in Fig. 4 arranged in its casing and with the front plate or cover removed. Fig. 5 is a detail View in perspective of'one of. the levers and certain parts connected therewith forming part of the shock "absorbers for the rear wheels. Fig. 6 is another detail view showing the manner of connecting-the sustaining springs to the levers. Fig. 7 is a detail view showing the manner in which concentric springsmay be employed.

The body A of the vehicle may beof any suitable construction. The side bars of the under frame are indicated at B and a portion of the actuating shaft at .C. The rear wheels D are each mounted on a stud axle d attached to a horizontally arranged lever within a casing F. E'ach stud axle d carries a spur wheel d" meshing with a pinion 6 on a stud shaft 6' attached to the lever E and each pinion c meshes with a spur wheel f attached to the driving shaft G. The casings F are attached to the under frame of the vehicle and are provided with removable outer side (pieces '9 which are the axis of the driving shaftG, ball-bean 9' between the lever and the shaft G being preferably provided and from this pivotal connection it extends rearwardly within the casing being supported from beneath by vertically arranged springs H which are connected to the casing and to the lever in the manner shown in-Fig. 6. Any desired number of rows of springs may be employed and each spring may comprise a series of concentric springs, as indicated in Fig. 7. Above each. lever is arranged a series of rows of springs I, the opposite ends of which may be seated in recesses 2' in the lever and casing, as shown in Fig. 6 and each spring I may comprise a series of conaxles d, e to move centric springs, as shown in Fig. 7. By this 5 down movements ofth efwheels'D l .municated to the "body 'of "the vehicle through the medium of thesprings H and" The front wheels J areeach mounted 'on- ,a stub axle j which is jointed to a bracket 'K projecting from a lever -K mounted-to swing vertically in a casing L, each of which casings has a main ortion Z formed preferably integrally wit the front cross-piece M of the under frame of the vehicle and said casing is also provided with a re'movable cover Z. The casings are secured to the side bars B of the under frame and they are preferably inclined at Z to permit the wheels to turn to the desired extent. 5 Each lever K is pivotally connected with a boss -k formed on the inside of the casing. Pref erably ball bearingsk are employed and 'the lever may be held in place by a headed bolt- N and: washer n, or many other suitable-way... The bracket "K may be formed into all fwith the lever K and this lever is,-a o ormed with recesses m to receive the upper compression s rings 0 (Fig. 4), the upper ends of whic rest in recesses 0 formed in the upper art of the casing.

, Springs P attached to t eunder side ofthe lever K are also attached to the bottomof the casing and the springs O and P normally hold the lever ina horizontal position. Preferably also each lever K is formed with a downwardly extending arm 0: to which is attached one or more horizontallyarranged springs X connected as shown with the front walls of the casings.

The levers K are adapted to move up and "down against the force of the springs O,

P and X and'by reason" of theircushionin ualities and by reason of the leverage a orded the vehicle is made-very easy I'HII'. ning and free from shocks or jolts.

. I claim as my invention:

'1. The combination with a vehicle frame,

of a wheel, its axle, a casing attached to the vehicle frame, a horizontally arranged lever pivotall mounted within the casing and to which t e wheel axle is connected and vertically' arranged springs interposed between the upper and lower sides of the lever and the top and bottom walls of the casing.

which is provided with a horizonta y extending bracket connected 'with the axle, and vertically arranged springs interposedbetween the upper and lower sides of the lever and the top and bottom walls of the casing.

3. Thecombination with a vehicleframe. of a casing attached to said frame formed with alaterally projecting boss, a horizontally arranged lever havin anti-friction I bearings on-said boss and ormed with a horizontallly Y projecting bracket, .a"wheel andaxle connected with said bracket, and

tween the upper and lower sides of the lever and the top and bottom Walls of the casing. 4. J The combination with a vehicle frame zontally arrangel lever pivotally mounted -within the casing and having a downwardly projecting arm, springs interposed between vertically arranged springs interposed beof a casing attached to said frame, a hori- I the upper and lower'sides ofthe lever and the topand bottom'walls of the casing, and a' horizontally arranged spring between said downwardly projecting arm and the front.
